For Loops in Python and the simulation of C-like loops with range. Fast to Code i.e. it is easier and faster to code a problem in Python than in C, It generates lists of arithmetic progressions: Example: >>> range(10) [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]. The output looks awfully familiar but the program code looks different. The first line uses As for goes through each element in a list it puts each into variable.

The output looks awfully familiar but the program code looks different. The first line uses As for goes through each element in a list it puts each into variable. Loops iterate over a block of code until test expression is false, but sometimes we wish to terminate the current iteration or even the whole loop without cheking. In this interactive tutorial, we.ll cover many essential Python idioms and techniques in depth, adding. So people is a list containing two items, each a 3item list.
